ST EAM-TRAP.

SPECIFICATION forming part of Letters Patent no. 400,718, dated April 2, 18 89.

Application filed October 23, 1888. Serial No. 288,939. (No model.)

To all whom, it may concern.-

Be it known that I, WALTER ANDERSON TAYLOR, a citizen of the United States, resid-- and claimed, reference being made to the accompanying drawings, in which- Figure 1 is an elevation of a steam-trap embodying my invention. Fig. 2 is a central vertical section,partly in elevation. Fig. 3 is a detail view of the adjustable bracket-rest. Fig. 4 is a detail plan view of the relief stuifing-box. Fig. 5 is a central vertical section of the same.

In the said drawings, the referenceletter A designates a receiver for condensed water connected at B to a manifold, O, to which manifold a number of connections, D, may be made to a number of steam coils. The connectionpipes D are shown broken off.. The manifold valve, some distance from the bottom.

enables the trap to be taken apart without disconnecting the pipe-connections by breaking the flange-joint at B. At E is the outlet The space in the receiver below the valve E serves as a trap for sediment that may enter the receiver with the water of condensation from G between the actuating end and the fulcrum N by means of a rigid rod, 0, witha lug at its lower end through which the valve stem passes, whereby it can be adjusted by means of jam-nuts m above and below, so as to set the valve E at the proper point.

P denotes an adjustable stop-bracket and lever-guide, which can be raised or lowered and set at any point by means of set-screws 6, thus changing the position of the lever G to any point above or below the center horizontal plane, enabling the waterto be carried at various permanent levels above the dischargevalve E. The stop-bracket and guide consist of the parallel arms at, having a stem, 0, adjustable in the bracketb,in which the stem 0 works. The bracket is bolted to the top of the trap-cover cl.

Upon the cover d of the trap is mounted a stuffing-box through which the stem I passes. This box is provided with the usual packingchamber, R, forming part of a gland, R, which has a female thread turning on 'a nipple, S, through which the stem I passes. ple-forms part of a relief-box,Q,having an outlet, S, which communicates with the outlet E. If any leakage takes place around the stem I, it will pass off through the pipe S and discharge-valve E. This form of stufling-box not only requires less packing, but need not be so tightly screwed up, and therefore exposes the stem I to-less friction. It has thus less liability of sticking or 'gumming and works more easily and with less expenditure of power, and is applicable to any purpose where stuffing-boxes are required.

In operation, the weight F being properly adjusted upon the lever G, the water of condensation entering the receiver A will raise the floatF until it is lifted to the upper dotted line position representing the upper Waterlevel, which is some distance above the valve E, at which point the valve E will begin to open by the further movement of the lever G, caused by the continued formation of the water of condensation, effecting the further lifting of the float F and the opening of the valve E full way, which will permit the surplus water in the receiver to pass out of the valve E and faster than the formation of the water of condensation, the water continuing to be dis- This ip charged until the float has again descended to its former lowered position,about four inches above the valve E, until another surplus of water accumulates in the receiver, when the action will be automatically repeated.

From the foregoing it will be seen that the float will be kept ina constant state of motion to prevent the liability of the float sticking, as in practice is found to occur when the float is at any time in a state of rest, which is the case where the action of the parts is such that a gradual or continuous discharge of the water of condensation takes place. Further, the valve E is always closed at a point below the low-water level to prevent the escape at any time of steam, whereby, together with the maintenance of the float in a constant state of action, not allowing it an opportunity to become wedged or clogged nor at any time to be exposed to the action or pressure of the steam, the valve will be preserved for a longer time in actual use. All sediment can be blown out at blow-off pipe T. By using a heavy float F, counterbalanced by a heavy weight L, I get a positive action of the trap, as the water in receding from the float F will give a great difference in weight over the counter-balance L, and vice versa, thus securing a positive action of the trap. By the use of a manifold, C, a great many coils can be drained through a single opening in the receiver.

The adjustable stirrup P can be set to regulate the rise and fall of the float F inside of fixed points.

What I claim is- 1. In a steam-trap, the combination, with a condensed-water vessel having a discharge located outside thereof below the water-level, a weighted float in the vessel having a stem rising through the top thereof, a lever pivoted above and outside the casing and connected with the float-stein, and an external rigid rod connecting the lever to the stem, of the external valve for moving the valve in unison with any movement of the lever, and a lever-stop bracket, and guide rising from a support on the top of the vessel and adjustable lengthwise in a vertical plane on said support to enable the water to be carried at different levels above the discharge-valve, substantially as described.

2. In a steam-trap, the combination, with a con densed-water vessel having an external discharge-valve, a leverpivoted above the vessel and connected with the float, and an external rigid connection between the lever and the valve-stem which moves the valve in unison with any movement of the lever, of a supporting-bracket rising from the top of the vessel, a stop-bracket and guide for the lever, having a stem movable lengthwise in a vertical plane in the supporting-bracket, and means for rigidly locking the stem and supportingbracket together, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WALTER ANDERSON TAYLOR.
